User TonybonJoby in our own forums has successfully flashed his XFX RX 480 graphics card with the BIOS from a Sapphire RX 580 Limited Edition (the one that runs at 1411 MHz Boost clocks, yes.) Having obtained the Sapphire's BIOS right here on TPU, he then flashed it onto his graphics card (which possesses a dual-BIOS setup; this is an important point which you should consider, as it gives you an extra safety net should anything go wrong) through ATIFlash. The newly-christened RX 580 thus smiles for the screenshot, with a stock clock of 1411 MHz, higher than most overclocks possible with the RX 480 cards, probably due to increased voltages on the BIOS level. The user then tested the card on The Witcher 3 and Furmark, with no problems having been reported. Just remember to back-up your BIOS with GPU-Z and make sure to peruse our forums for some details on this flashing process before you get the proverbial grease on your elbows.

Essentially, this may allow you to bypass some artificial overclocking limitation with your graphics card, probably by increased voltages on different power states of the card. You should do this at your own risk, and remember, the only guaranteed way of getting an RX 580 is... you guessed it, buying an RX 580. However, this might also give you an extra performance boost, and free performance is always good, right?

With any kind of luck, the 470 may flash to a 570 as well...the little extra clocking headroom may be worth it. I'd be skeptical if I were flashing a 'lesser-binned' or budget oriented card model. Will wait and see if/when someone tries flashing a Sapphire 470 4GB Nitro+ card 'up' to a 570 4GB Nitro+...these cards are near identical as far as hardware and construction / lay-out are concerned...fingers crossed! Hope it's not exclusive to 'Limited Edition' firmware...even though there's some talented n determined modders out there.

I was impressed the 480 could be flashed to 580 spec so that it could reap the benefits of the added features in the amd drivers. Then I realised the 580 doesnt have new features just better clocks and a new name.

It's deceptive I remembered they rebranded the 7970 as the 200 and 300 series then RX 400 series with better fab and a few tweaks meaning 2 big rebrands and recycling the architecture. Recently I was reminded about the 7970 ghz edition which does the same thing as the 580 adding some extra mhz.
Bring on vega :)

Deceptive like, Nvidia did it first? Or deceptive like Nvidia using differing cores for the same card for three generations? Or deceptive like 3.5GB memory?

Also, 7970 became 280X and nothing more. Different cores were used in the 3xx series, and the 4xx series.

Differences are meh just the number of recycles of this architecture with releases now.

I do really want the 1070 to get rebranded as an 1170 or 1160 or even a bios editor to get released just so I can flash my 1070. I can hit 2050mhz and suspect I could hit 2200mhz on 1.2v as oppose to the 1.093v I'm stuck on.

First? Maybe. But they havent done it in three generations if my memory serves (770?). AMD's rebrands were plentiful the past three generations. Hawaii, Tonga, Pitcairin...Polaris. like 8 cards were rebrands with clock differences.

I don't think Nvidia will do a rebrand but looking at the 1.093v voltages they're using they might? The last time they did was with the 600 series where they used 1.175v while the still safe voltage was 1.212v used in the 700 series and had hard boost limits set in bios which caused the driver to crash if you go beyond that overclock offset.
The worst case I found of this was with a 660 ti direct cu II. They made various versions of these cards and I had the slowest with stock speeds with 980mhz boost which went to 1100 in game. To my surprise the hard boost limit was set to 1100mhz but after going through making a custom bios and tuning an overclock I could run 1280mhz without issue. Admittedly there was a bios update on the Asus site which silently patched the boost limit to 1150mhz.

Adam Freeman said:I don't know what is the point in going into the hassle of flashing the bios to transform an Rx 480 to Rx 580. Flashing the bios won't transform a lower binned gpu to a better binned one that overclocks better. It's easier to try manual overclocking and adjust gpu vcore and clockspeed to obtain the best combination of voltage and frequency that result in higher performance with acceptable power draw.

Can you link to proof of this? If you're referring to the different core count, the rx460 has 1024 as well, but needs a bios mod to unlock (driver needs patching, so a signed rx560 bios would be convenient). That said, last I've read, the rx560 isn't out yet and there's conflicting reports about whether it'll actually have 1024 core or still just 896.

You're in luck. Looks like that's the only bios currently posted, and has been a confirmed success for what you're trying to do. I flashed it as well on my strix, but because the outputs are different, I've only got use of one dvi port. Otherwise is working just fine.
